Abstract (en)
[origin: WO0163947A1] A method of call control in a packet-switched radio telecommunication network that minimizes delays in launching a voice call from a first Internet Protocol (IP)-based mobile station (MS(11)) to a second IP-based MS (12). The method includes the steps of preventing voice traffic from being routed to an Internet Service Provider (ISP), and setting up an optimized path for voice traffic from the first MS to the second MS. The optimized path may be set up by creating (48, 49, 63, 64, 65) a shortest route tunnel (53) between a first serving GPRS service node (SGSN1(13)) serving the first MS and a second SGSN (SGSN2(14)) serving the second MS. Alternatively, the tunnel (66) may be established (48, 49, 63, 64, 65) between the base station controllers (BSCs(61, 62)) of each MS's serving radio base station.
